Description
The MCP8063 device is a highly integrated 3-phase,
full-wave sensorless driver for brushless motors. It
features a 180° sinusoidal drive, high torque output,
and silent drive. Its integrated features and the wide
power supply range (2V to 14V) make the MCP8063 an
ideal candidate for a broad range of motor
characteristics, requiring no external tuning. Speed
control can be achieved through either power supply
modulation (PSM) or pulse-width modulation (PWM).
Due to the compact packaging and minimum bill of
materials (power transistors integrated, no Hall sensor,
no external tuning), the MCP8063 is optimized for fan
applications that require high efficiency and low
acoustic noise at competitive costs. Frequency
generator output enables precision speed control in
closed-loop applications. The MCP8063 driver
includes a Lock-Up Protection mode, which turns off
the output current when the motor is under lock
condition, and an automatic recovery that enables the
fan to restart when the lock condition is removed.
Features such as motor overcurrent limitation and
thermal shutdown protection improve motor system
reliability without additional efforts from design
engineers.
The MCP8063 is available in a compact
thermally-enhanced 8-lead 4 mm x 4 mm DFN
package with exposed pad.
